नाहं देहो न मे देहः केवलोऽहं सनातनः ।एकमेवाद्वितीयं वै ब्रह्मणो नेह किञ्चन ॥ २८ ॥
In plain words
I am not this body, and this body is not mine. I am alone, eternal. One — one only, with no second — and apart from Brahman there is nothing here at all.
Close to the Sanskrit
I am not the body, nor is the body mine; I am alone, eternal. One only, without a second indeed — apart from Brahman there is not anything here.
